But if you think it's reverse sexism, because there's no International Men's Day, and if there was an International Men's Day then all the femi-Nazis would be all screaming about discrimination and burning their bras and so on, then you're wrong. International Men's Day is November 19:

Objectives of International Men's Day include a focus on men's and boy's health, improving gender relations, promoting gender equality, and highlighting positive male role models. It is an occasion for men to celebrate their achievements and contributions, in particular their contributions to community, family, marriage, and child care while highlighting the discrimination against them.

Obviously, we all realise that the white man is the most oppressed creature in the world, cruelly deprived of as many as 10 per cent of boardroom positions and 25 per cent of seats in the House of Commons. And we must all fight without pause against the injustice of it. But don't worry, chaps: at least the battle for our own day to mark the struggle has been won.
